Title: Key Technologies of spectrum sharing for integrated satellite and terrestrial networks
Prof. Guo Qing received B.S. degree in radio engineering from Beijing Institute of Posts and Telecommunications in 1985, M.S. and Ph.D. degrees in information and communication engineering from Harbin Institute of Technology in 1990 and 1998 respectively. He is the dean of School of Electronics and Information Engineering at Harbin Institute of Technology, director of Key Laboratory of Wideband Wireless Communications and Networks, Heilongjiang. His research interests are broadband satellite communications, space information networks, small satellite TT&C and wireless communication networks etc. He has published 1 authored book and more than 150 papers in journals and international conferences.
With the different application scenarios (marine communication, deep space communication and emergency communication, etc.), the integrated satellite and terrestrial network faces a variety of business requirements, including communication, remote sensing, measurement and control, positioning, Internet of vehicles, Internet of things and other services, as well as the different QoS requirements. However, the spectrum, orbit, power, storage, processing capacity and other resources of the integrated satellite and terrestrial networks are limited. Aiming at the problems of service diversification and system flexible expansion of business and requirements, this report will introduce the key technologies of spectrum sharing networks, such as spectrum sensing based on cognitive, waveform design, resource management based on interference suppression and software defined network.
